I think it over again !!
We must separate realtime backfill need (online) and historical test (offline)
,for historical ,using ascii source to download from source seller -file size up to 7GB
(MC limitation ) .
For AM , I use mldownloader to download globally many country's EOD data from 1962til now

For realtime ,if your indicator need MA800 ,then larger than 800 bar backfill is enough . |
